Triboelectric nanogenerator‐based environmental energy harvesting technology is not only for the applications of the Internet of Things but also has a revolutionary impact on traditional industrial fields. Advanced oil and natural gas drilling technology, for example, horizontal drilling and hydraulic fracturing, has important environmental concerns about water and atmospheric pollution. High data transmission rates and visual and real‐time monitoring are considered potential solutions to avoid both economic and environmental problems. The current data transmission rate for oil and gas drilling is just 5–40 bits per second, despite commercial fifth generation (5G) and future sixth generation (6G) wireless communication technologies with data rates of 10–1000 gigabits per second. Herein, a self‐powered while‐drilling communications system based on a triboelectric nanogenerator is reported. The data transmission rate is three orders of magnitude higher than the traditional method. The free‐standing layered mode triboelectric nanogenerators (FS‐TENGs) can achieve fast information transfer using the harvested energy from the vibration of the pipe wall.
Good natural ventilation can improve the comfort of campus dormitories and effectively avoid pollution caused by particle accumulation. Parametric design can effectively address the feedback and connection between building performance analysis and design. This study employs an architect-friendly digital design method based on the Rhino/Grasshopper parametric platform. It takes campus dormitories in the cold region as a case, using parameterized digital tools, such as the Butterfly plugin to simulate wind performance under three influencing factors: building layout, opening position, and building façade (shape and spoiler). Finally, the optimal design that can simultaneously meet the local winter and summer wind environment requirements is selected and validated. In addition, the reasonable design of external balconies and bathrooms in a dormitory can form buffer spaces to achieve effective wind shelter and insulation effects in cold regions. This article describes how to use digital tools to quickly and easily optimize the design of building forms based on wind simulations to promote campus sustainability.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
